Product Description
Built for serious production work, this 2020 Komatsu PC450-7 is a 45-ton hydraulic excavator available now from Zhejiang, China — inspected, serviced, and ready to move dirt from day one. Powered by a Komatsu SAA6D125E-3 six-cylinder, water-cooled, turbocharged engine producing 259 kW at 1,850 RPM, this machine delivers the raw force required for deep excavation, heavy demolition, and high-volume material handling without compromise.
- Digging Performance: 278 kN bucket digging force and 233 kN arm digging force, with a maximum digging depth of 7,790 mm and a maximum digging radius of 12,005 mm
- Bucket Capacity: 2.1 m³ backhoe bucket for aggressive cycle times on bulk earthmoving and trenching operations
- Powertrain: 11.04L displacement, direct injection, turbocharged engine with electronic speed regulation and water-cooling for sustained output under heavy load
- Hydraulic System: Dual axial plunger travel motors, main pump maximum flow of 690 L/min, and a travel hydraulic circuit rated at 37.3 MPa
- Mobility: Three-speed travel up to 5.5 km/h with 70% gradeability and 600/700 mm track shoe options for varied terrain
- Transport Dimensions: 12,040 mm (L) × 3,340 mm (W) × 3,660 mm (H) — straightforward to load and ship internationally
